We only have built-in types. I think we have 54 of them, 32 integer, 12 float, and 10 mask. I hadn't thought about user-defined sizeless types, and hope that I don't have to support that. > If the hook is enough, I guess there are three ways we can go: > (1) Add hooks for both targets, with similar functionality.

I'm a little surprised that you can't support alignof on a vector type, I would think that depends on the base type for the vector, but maybe this is a difference between SVE and RVV, or maybe I just haven't gotten far enough to find the problem yet. Otherwise it looks like this would also work for the RVV support. Jim
